Abstract

Surface roughness effects on the dynamic responses of hydrodynamic journal bearing have attracted many researchers’ attention for developing both more efficient lubrication mechanisms and accurate online diagnostics. This paper develops the model of dimensionless Reynolds equation based on the short bearing lubrication theory, which considers the influence of the surface profiles parameters. Various random surfaces are generated under the constraints of root mean square (RMS) and correlation-length, which are used to discuss the effect of surface characteristics on the pressure distributions of journal bearings. The results based on a series of simulations show that anisotropic surface obviously affects the pressure distributions. RMS and correlation-length of surface profiles act on the amplitude and density of pressures distributions, respectively. These results investigate the effectiveness of the model and the findings are meaningful to detect the early faults of journal bearings.
